The problem with catching big female bass during the spawn is a high percentage are the anglers personal best catch and get over handled or taken home. When female bass spawn it is stressful and a few don't survive as a result, without being caught. Add the stress of being caught, put into a livewell, weighed, photographed etc and a stressed bass to start with, the odds increase they may die. These bass don't always roll over and die instantly, they swim around like a zombie and starve unable or no desire to chase or catch food.
If we use Dottie as a catch and release example, she was a star. Dottie was always caught off a bed, never documented being caught any other time of the year. Dixon lake is small, the weigh station minutes away from where Dottie was caught so she didn't stay in a livewell more than a few minutes and was handled by expert trophy bass anglers and biologists, ideal conditions few other giant bass had.
